Thank you for responding. Nice to hear that it actually should work. However, when I tried entering multiple words in the filter I get no hits when exceeding one word.
I also looked at your demo page to see if there was any files with more than one word, but they were all separated with underscore so I was not able to test the function on your demo page.
Before I modify the .js file, is there anything that could be misconfigured or not working?
